The 1990s saw a new wave of creative vitality and fan interest in comics’ original superhero, with four tightly connected monthly series bringing the Man of Steel to new heights: Superman, Adventures of Superman, Action Comics, and Superman: The Man of Steel.
These four series, while continuing to retain their own distinct voices, worked closely in tandem with each other, telling a detailed larger narrative of Superman’s never-ending battle. In turn, DC added numbered triangle icons to each cover, indicating to readers exactly where in the story a given Superman issue would fall—ushering in what readers fondly remember as “the triangle era.”
